Despite all the hype about this Korean "kaiju" monster movie I was extremely disappointed in this flick. The story starts with a lab guy dumping gallons of chemicals into the nearby river, where it presumably mutates the local wildlife and ultimately spawns the title creature. It looks like a giant mud-puppy (big salamander) crossed with the monster from TREMORS. And all the effects sequences of it are amazing and almost worth the price of renting the movie. However, these aren't long enough and too much time is spent on the dynamics of a disfunctional family, which I did not find interesting or entertaining. The daughter of one of the guys is captured by the creature and she calls on a cell phone, saying she's being kept in the big nearby sewers. They go after her but the government says that the creature is the host of some deadly virus and round up everyone to keep them under quaranty. The family escapes and goes to look for the girl in the sewers.

As I said, if more time was spent on the monster and less on the humans this would have been a much better movie.
